This works, however please note there are more cleaner ways to achieve this. Knowing those will definitely help in the future.

This fulfils the requirements, now think of the below:
- What will happen if we inverse the
if conditioncheck. - What does
hasOwnPropertymethod return, do we need explicit return statement
This will help make this more better and less cluttered!

Maybe a typo here, country is a constant, can it be redeclared?

Does currency exist in the global and local scope?

There is cleaner way de-structuring of accessing the values, if we expect the array to have fixed number of items,

What if we start at 0 when the key is undefined and then increment by 1 if exists. Will shorten the code for sure.

This is asking why does the current invert function returns {key: 2} when { a: 1, b: 2 } is passed as argument. Shouldn't the function return {"1": "a", "2": "b"}?

This will create key key in the object invertedObj, is that our goal (make key to value and value to key).
